controller ported from NetBSD. It supports the following Gigabit
Ethernet adapters.
o Antares Microsystems Gigabit Ethernet
o ASUS NX1101 Gigabit Ethernet
o D-Link DL-4000 Gigabit Ethernet
o IC Plus IP1000A Gigabit Ethernet
o Sundance ST-2021 Gigabit Ethernet
o Sundance ST-2023 Gigabit Ethernet
o Sundance TC9021 Gigabit Ethernet
o Tamarack TC9021 Gigabit Ethernet
The IP1000A Gigabit Ethernet is also found on some motherboards
(LOM) from ABIT.
Unlike NetBSD stge(4) it does not require promiscuous mode operation
to revice packet and it supports all hardware features(TCP/UDP/IP
checksum offload, VLAN tag stripping/insertion features and JUMBO
frame) and polling(4).
Due to lack of hardware, hardwares that have TBI trantransceivers
were not tested at all.
Special thanks to wpaul who provided valauble datasheet for the
controller and helped to debug jumbo frame related issues. Whitout
his datasheet I would have spent many hours to debug this chip.
Tested on: i386, sparc64
